Hi There,
I need some advice and help.
I want to upgrade My old faithfully 6200, so I have obtained a 6500
Motherboard of ebay at a very good price.
The number on the board is 820-0816c, this seems to make it a 225 Mhz
variation am I correct ?.
Pass.
It has 1 x Comms, 1 x PCI, 1 x Cache, 2 x RAM slots. I was supplied
with 1 x 16 Mb of RAM, I do not think this RAM will work with this
board.
You need special RAM. I forget the details, but the 6400 pages at Low
End Mac and the 6400 Zone will have all the details.
In order to use it I need to install 2 x 64 Mb of basic RAM or more if
it will identify more than 128 Mb is this possible would I need RAM
slot doublers?.
You can't go beyond 128Mb under any circumstaances. This issue was
researched to death a few years ago. Sorry.
I will also need to install Cache RAM not sure what to look for here
size or type ?.
L2 cache cards used to appear on eBay. They make a _huge_ difference to
performance. They are specific to the 5400/6400/5500/6500.
A PRAM battery should not be any problem I assume it is different than
the 6200 again what do I look for.
It's the cube-shaped one that Maplin used to list.
Will the power supply of the 6200 work with the 6500 if it does will
it limit the use of the 6500 board ?. If I get my hands on a 6500
power supply will it be a straight replacement for the 6200 or will
some other adjustment's be needed ?.
Some 6200 supplies had 3.3v lines; others didn't. If yours hasn't, you
won't be able to use the PCI slots, but the main board should be OK.
Are there any other problems that any one could think of that I have
over looked.
I just hope that a fully working 6500 wouldn't have been cheaper than
the board you have plus all the extras you look as if you'll have to
buy.
Also could any one help with supplying the items at a good price.
eBay may well be your best bet.
